Heft is a simple tool for testing the performance of web servers under load.
- HTTP load testing: Simulates multiple concurrent users accessing a web server to assess its performance under stress.
- GET requests only: Currently supports testing GET requests, the most common type of HTTP request.
- Simple design: Likely offers a user-friendly CLI and straightforward setup for ease of use.
- Measuring website performance: Evaluating how a website handles various traffic loads.
- Identifying bottlenecks: Pinpointing areas of a website that might slow down under heavy traffic.
- Testing server capacity: Assessing how many concurrent users a server can handle before performance degrades. Optimizing website performance: Using results to make informed decisions about website optimization strategies.
Ensure you have Go installed on your system. Check by running go version in your terminal.
Get the code:
- Clone the repository using
git clone https://github.com/ankitsridhar16/heft.git
Build the executable:
Run go build cmd/heft/heft.go in the terminal to create the Heft executable file.
Navigate to the build directory:
-
In your terminal, go to the directory where the Heft executable was built (usually the project's root directory).
- Execute the command:
Run the following command to start Heft:
./heft -u <URL> [-n <num_requests>] [-c <concurrent_requests>] - Replace
<URL>with the actual URL you want to test. Optionally, specify:- -n: Number of requests to perform (default: 1).
- -c: Number of concurrent requests to run (default: 1).
./heft -u https://www.example.com -n 100 -c 10Output:
- Execute the command:
Run the following command to start Heft:
Heft will perform the load test and print the results to the console, including:
- Total successful requests (2XX status codes)
- Failed requests (5XX status codes)
- Requests per second
- Total request time (minimum, maximum, and mean)
- Time to first byte (minimum, maximum, and mean)
- Time to last byte (minimum, maximum, and mean)
